    MEMO

    In a bustling revival of a beloved smartwatch legacy, Eric Migi, founder of Core Devices, unboxes the first pre-production batch of Pebble Time 2 units during a recent Tick Talk episode. These e-paper wonders, successors to the original Pebble that captivated Kickstarter backers a decade ago, arrive amid a community yearning for assurance. The original Pebble Tech's 2016 demise left users in limbo, with watches ticking on but apps vanishing from stores due to unpaid fees. Migi addresses this head-on, pledging a sustainable path through a lean, self-funded operation that sidesteps venture pitfalls, ensuring steady manufacturing without the boom-and-bust cycles of yesteryear.

    Central to this relaunch is an unyielding commitment to open source, now elevated to 100% across Pebble's ecosystem. Previously, only the SDK was accessible; today, PebbleOS—the real-time operating system that powers the watches—joins the fully rebuilt mobile app in Kotlin multi-platform and developer tools on GitHub. This move, inspired by Google's 2023 release of PebbleOS under Apache 2, allows anyone to compile, modify, and deploy code. Migi reflects on past pains: iPhone users sidelined for years without an official app, a void the Rebble Foundation patched with a centralized store preserving 15,000 community creations. Now, the new app supports multiple feeds, echoing open-source package managers, while daily archives to archive.org guard against server failures.

    Hardware sustainability takes tangible form in Pebble Time 2's design. Screws secure the back cover, enabling battery swaps—a fix for the original's sealed fate after five to ten years. Published schematics for the Pebble 2 Duo invite tinkerers to craft compatible devices, from watches to beyond. Migi demos the prototypes: a larger 1.9-inch screen scales vintage watch faces like Block Slide and Nine Cats, displaying notifications with unprecedented clarity. Colors pop—black-on-black, Rivian blue accents—via polycarbonate and PVD-coated steel, with a plastic layer isolating the Bluetooth antenna for reliable connectivity.

    Production hurdles loom, however. Amid design verification, Chinese New Year's January shutdown threatens delays, pushing mass output to February-March and deliveries to spring. Yet lessons from shipping Pebble 2 Duo bolster confidence: small batches in January could fulfill initial pre-orders, with color confirmations emailed soon. Internals revealed—a heart rate monitor, linear actuator, touchscreen in testing—promise interactivity, from games like Obelisk to multi-timezone faces for globe-trotters.

    This relaunch isn't mere nostalgia; it's a blueprint for tech longevity. By decentralizing software, modularizing hardware, and centering community, Migi ensures Pebble thrives as a collaborative endeavor. As he quips, he'll be its last user—actions proving words, fostering a ecosystem where innovation persists, unbowed by corporate tides.
